BitField Attribute

Enables bit field masking from the Inspector.

Installation

Copy BitFieldAttribute.cs and the Editor folder containing BitFieldAttributeDrawer.cs to your Assets folder.

Usage

Decorate your enumeration fields with the [BitField] attribute.

Examples:

[Flags]
public enum FlagsEnum
{
  FLAG_1 = 1,
  FLAG_2 = 2,
  FLAG_3 = 4,
  FLAG_4 = 8
}

public enum Int32Enum : int
{
  FLAG_1 = 1 << 0,
  FLAG_2 = 1 << 1,
  FLAG_3 = 1 << 2,
  FLAG_4 = 1 << 3
}

public enum ShortEnum : short
{
  FLAG_1 = 0x1,
  FLAG_2 = 0x2,
  FLAG_3 = 0x4,
  FLAG_4 = 0x8
}

public enum SByteEnum : sbyte
{
  FLAG_1 = 0x1,
  FLAG_2 = 0x2,
  FLAG_3 = 0x4,
  FLAG_4 = 0x8
}

[BitField]
public FlagsEnum FlagsField;

[BitField]
public SByteEnum SByteField;

[BitField]
public ShortEnum ShortField;

[BitField]
public Int32Enum Int32Field;

Limitations

Underlying types of unsigned integers or integers greater than 32bit are not support by the Unity Editor.

The fixed flag values are:

• Nothing = 0
• Everything = -1
